Question

When employed as a part-time maintenance person, a PHY210 student is using pruning shears such as the pair shown, to cut a branch from a tree near the Science Building, we all agree that it is better to insert the branch closer to the hinge than near the end of the shears. Which one of the following statements best explains the reason this observation is true? Select one: a.The torque exerted on the shears yields the greatest force on the branch near the hinge o b. The long handles determine the force exerted on the branch, which is the same no matter where branch is placed. c.The torque acting on the branch is largest near the hinge d. The torque acting on the branch is smallest near the hinge. s e. The same torque is exerted on the shears and the branch, regardless of the force applied to the handl

Explanation / Answer

If we will place is closer to hing ,the torque required to cut the branch will be less so we have to apply less force on the other end .So if it is placed near hinge ,force on branch will be more for the same torque applied by shear

so correct option is

option (a)
